Application filed December 1, 1921. Serial No. 519,130.

Vented certain Improvements in Lasting.

Machines, of which the following description, in connection with the accompanying drawings, 1s a specification, like reference Y characters on the drawings indicating like inthe lasting of boots and shoes.

parts in the several figures.

This invention relates to machines for use The invention is herein illustrated in its application to means for lasting the toes of shoes, but it will be recognized that in many of its aspects the invention is also applicable to.

the lasting of other portions of shoes, for example to heel end lasting.

In one important aspect, the invention relates to a type of organization comprising overwiping means and upper clamping means in which the operation of one of said means is dependent upon the operation of the other, for example where a clamping band is applied about an end of a shoe by the action of the wiper operating means. As applied to an organization of this `general type, the invention aims to provide for better control than heretofore of the clamping pressure and for greater facility in the operation of the overwiping means. With these and other objects in View, a feature of the invention consists y in a novel construction and arrangement of clamp applying and controlling means, the construction shown comprising a cam control for an end em-v bracing band whereby the band is closed about the end of the shoe during a portion of the operative movement of the end embracing wipers and is then maintained in closed position withthe clamping pressure substantially unchanged during further movement of the wipers andV without substantial resistance to such further wiper movement. The invention thushas important advantages, for example, in its application to a well-known type of McKay toe lasting mechanism wherein the upper is clamped about the toe by a band which is closed as the irrespective of the shape.

wipers are advanced, and in the use of which it s customary to reciprocate the wipers a plurality of times without entirely retracting them from over the bottom of the shoe and then to'maintain them in partially closed position for the tacking operation. IAsapplied to such an organization,the present invention permits the repeated movements of the wipersto be effected without variation in the clamping pressure applied about the toe, and without resistance from the clamping means, which is locked in pressure applying position without any tendency to withdraw the wipers from over the shoevbottom. A further advantage is that substantial uniformity is insured in the clamping pressure applied to different shoes of the same size and style. i

A further feature of the invention consists in novel means affording provision for adjustment of a shoe end embracing band to conform to different shapes of shoes and to determine the clamping pressure applied in different locations about the end of: a shoe. In its embodiment of this feature the construction shown comprises .unyielding connections between the ends of the band and the usual band closing slides, lwith provision for relative adjustment between the slides and the ends of the band in directions lengthwise of the' shoe.' rIhe band may thus be adjusted toA conform to a Wide range of shapes including narrow toes and comparatively widc or blunt toes and to applythe required pressure to the corners of the toe As a further provision for conformity to dierent shapes and sizes, and to determine the pressure ap- NIU . granted on November 12, 1918 upon an application of Matthias Brock, which mayl be consulted for a better understanding ot such features of the general organization of the machine as are not hereinafter described. The machine comprises a support or rest 2 for the toe end portion of shoe materials assembled upon a last the heel end portion of whichis mounted upon the usual last pin (not herein shown). For embracing and clamping the upper materials about the toe of the last the machine is provided with a toe band comprising the usual flexible facing 4 and the supporting chain 6. For wiping the upper upwardly about the toe of the .shoe and for gatheringand wiping its margin inwardly over the bottom ot the last, the machine has end embracing wiper plates 8 which are advanced and closed by operating means comprising a rod or plunger 10 and a hand lever 12 connected to said plunger by a link 14. It will be understood that the wipers are first advanced and closed about the toe below the plane ot the shoe bottom and are then elevated by treadle means for upwiping the upper about the toe while they are maintained in close engagement with the upper materials by manipulation of the lever 12, such upwiping movement being effected by the elevation of the toe lasting head upon which both the wipers and the toe embracing band are supported. After the wipers have been elevated to the overwipipng plane they are further advanced and closed by manipulation of the lever 12 to gather and wipe the margin of the upper inwardly over the bottom of the last and to iron down the pleats in the upper material. 0n McKay shoe work the wipers are moved for a comparatively long distance inwardly from the edge of the shoe bottom, and in accordance with the usual practice they are then partially retracted and again closed inwardly a plurality of times, after which they are positioned with their edges partially retracted to permit the upper fastening tacks to be driven.

The toe embracing band is advanced and closed about the 'toe of the shoe through closing members or slides 16 which are movable lengthwise of the shoe and are connected to the opposite end portions of the band by mechanism to be more particularly described hereinafter. At their outer ends the slides 16 are pivotally connected to a cross bar 18 which is in turn connected midway between its opposite ends to a slide 20. EX- tending from the slide 2O is a stem 22 (Fig. 3) on which is slidingly mounted a cross head 24, the stem being provided with a co1- lar 26 to limit the outward movement of the cross-head along the stem. Adjustably threaded in ears 28 on the slide 20, in the construction herein shown, are rods 30 which extend outwardly through the cross head 24 and are squared at their outer ends to fac-ilitate their adjustment. Encircling the rods 30 are springs 32 which are partially housed within the cross head 24 and bear at their outer ends on the cross head and at their opposite ends on collars 34 on the rods.

Operative movement is imparted yieldingly to the band closing slide 20 through the cross head 24 and the springs 32 by connections which receive their operative movement from the wiper operating hand lever 12. For the purposes in view, the wiper operating plunger 10 carries a cam block 36 provided on its opposite sides with path cams 38 in which are mounted rolls 40 carried by the upper ends of bell-crank levers 42 mounted on pivots 44 on the toe lasting head. At their lower ends the levers 42 are connected by links 46 to the opposite sides of the cross head 24. It will be understood that the cams, levers and links are duplicated merely or strength and to establish a better balance between the 'opposite side portions of the mechanism. The path cams 38 are so shaped that as the wiper operating plunger 10 is advanced the bell-crank levers 42 are operated to move the cross-head 24 toward the right (Fig. 2) and to impart yieldingly through the springs 32 operative band closing movement to the` slide 20. hile the cams may be variously,A shaped to cause the band to be applied in any desired time relation to the movement of the wipers, the construction herein shown is such that the wipers will receive a slight advancing and closing movement relatively to theband, to positiontheir wiping edges in effective engagement with the upper materials for the upwiping operation, before the band receives any substantial closing movement. Immediately upon further advancing movement of the wipers, to wipe the upperinwardly over the bottom of the last, the. band is closed firmly about the toe by the operation on the levers 42 of portions of the cams which are inclined to the direction of movement of the plunger 10. It will be noted that the lower portions of the cams 38 are substantially straight and parallel to the direction of movement of the plunger 10. Vhen the rolls 40 arrive in position to engage these lower portions of the cams, the wipers may be further advanced and closed without the application of further pressure to the band. The operator is thus enabled to close the `thus aplurality of times and then positioned lwith their edges partially retracted to permit the tacks to be driven while the levers 42 are still under control of thelo-wer straight portions of cams. Thereafter the lever 12 will be further retracted to withdraw the wipers from over the shoe bottom and to effect the opening of the band.,

" The intermediate portion of the-toe band is supported and controlled bymechanism substantially as illustrated in' Patent No. 1,284,870, ywhereby the band may be adjusted relatively to the wipers in directions lengthwise of the shoe through the operation of a hand wheel 48, the controlling means also permitting the band to be moved forwardly toward the toe end face of the shoe against the resistance of the usual 'spring 50 in response to the pull applied at its` end portions. The yclosing slides 16 4in their `lengthwise movements are wedged toward and from the sides of the shoe to close and to open the band laterally of the shoe by positive means comprising rolls 51 which engage the slides in slots 52 formed in inclined relation to the length of the slides.` vThe connections between the closing slides 16 and the ends of the band comprise arms 53 which are mounted on the ends of the slides and are connected by pivots 54 to the ends of the band chain. AThe arms 53 are slotted horizontally (Fig. 4) to embrace the ends of the slides 16 andare also provided with vertical slots 56 to receive pins 58 which are securedy to the ends of the slides. The arms 53 are adjustably positioned with respect to movement laterally of the shoe by means of thumb nuts 60 which are swiveled iny the ends of the arms and are Athreaded on rods 62 the inner ends ofwhich are connected to the pins 58. By turning movements of the nuts 60 the arms may be adjusted inwardly or outwardly, independently of each other, to vary and determine the pressures applied by the end portions of the band at the opposits sides of the shoe.

The arms 53 are normally held from turn-y ing about the pins 58 by means of rods 64 which are swiveled on pins 66 on the outer ends of the arms 1an-d extend through ears 68 on the slides 16. Nuts 70 are swiveled in the ears'68 and are threaded on the ends of the rods 64 for "swinging thearms 53 adjustably about the pins 58 and for maintaining them in adjusted position. Through the adjustable connections thus provided the contour of the band may be varied and adapted to different shapes and sizes of shoes. For example, if the band were to operate upon a shoe having a wider and lessT pointed toe than that for which it is adjusted in Fig. 1 of the drawings, the rods 64 would be operated t-o swing the pivotal 'connections 54 between the arms 52 and the ends of the band toward the left, thus permitting the toe end portion of the band to spread out in conformity to the contour of the different shape of toe. To` adapt the band for a more pointed toe, the pivotal connections 54 would'be swung toward the right (Fig. l), thus contracting the toe end of the inward or outward movement of one or both of the arms 53 as may be required by the width and the shape of the toe will be made by turning the nuts 60. In practice a shoe will preferably be mounted in the machine and the band then adjusted' to fit the toe and to apply the required degree of pressure in the differentl locations about the toe, after which substantially the same pressure will be applied on all shoes of the same size and style without the need for further adjustment.

It will'be evident that the effectiveness of the means provided for adjusting the band to the dil'erent shapes of toes and for insuring the required pressure about the cornersv of the toe is increased by reason of the fact that the connections between' the ends of the band and the closing slides 16 are unyielding in the direction of the length of the shoe in the operation of applying the band about sureunder which the slide 20 is operated may be varied as desired by adjustment of the compression of the springs 32 through turning movement of the rods 30. Itwill be evident that such adjustment of these 'springs is eected without varying the position of the band or the relative positions the band and the wipers. r
